COLLAPSIBLE BOATM Application 4tiled Ap.'il l. 1922 To all w/wfm it mayConcern:

Be-it known that I, lauren S. Vl'ieaoV a citizen ofthe United States ofAmerica, and resident of the town of Ravensdale, in the county of. King,State of` l-Vasliington, have invented certain neat7 and usefulImprovementsinv Collapsible Boats, of which the following is aspecification.

My invention relates, to collapsible boats.

The object of my invention is to provide alboaft sot constructed that itmaybe taken apertand collapsed -into a package of such a sizeffthat itmay beconveniently transported articularly -upon ordinary passengerautom@ iles It isi alsoiian object to keep the Weight small enoughl andthe size of the paelfage of such character that it may also becalrieelVby a single man lfor ordinary distf1-Dices Y Theifeatnres of myinvention which I be lieve; to be new and upon which I desire toobtains. patent will behereinafter set forth and thenparfticular-lyf-de-tiined,by the claims The-accompanying drawings showiiiy in vention embodied in the typeof constructionwhich 'I now. preferto use.

The construction of my boat is one ernployinga collapsible frame workwhich may be assembled in the form of a boat, over which is then-placeda cover or skin composed of canvas or any other suitable fabric. Thebottom of the boat employs four plates l` each being of thin materialas* sheet metal and representintY n quarter seo tion of the bottom ofthe boat.. These plates when in use are positioned with edges in Contactso that the combination outlines the body of the boat. The line otdivision lieV tween the plates is along the longitudinal and transi'erseCentral axes. The (We plates at opposite Sides of the longitudinalrentriil Serial. N01' 548,656.
